Vemco VR4-UWM Checklist

Use these checklists to help you prepare
your VR4-UWM for deployment, successfully
deploy the receiver, and gather the data
when you return to the deployment location.
Equipment

F
to field day and/or make sure you have
a "clean power source" to power the
unit.
Benthos surface modem transducer

F
Do not bump the VR4-UWM
hydrophone or expose it
to extreme temperature
variations.
Doing so may damage the receiver and
render it unable to detect transmitters.
Preparation - On Land
Make sure latest VUE version is installed on PC, including the latest manuals.
F
Start a study using VUE software and Bluetooth communication (exit Suspend mode).
F
Perform an in-air test (see manual) using Bluetooth communication.
F

F
VR4-UWM Receiver
Electronics inside the case must NEVER come in
contact with any water or the VR4-UWM will be
damaged.
Important
Initialize VR4-UWM before deploying.
„
the magnet and the VUE software (Bluetooth
communication) and start recording to remove the
receiver from Suspend mode.
Do not open the case except to change battery.
„
This receiver was sealed and pressure tested prior to
shipping.
Never deploy a VR4-UWM beyond 500 meters depth.
„
Do not deploy VR4-UWM receivers with the same
„
modem address within 5 km of each other. Doing
so could disable modem communications with the
surface acoustic modem.
Do not allow the VR4-UWM to be dropped or struck
„
against other objects.
Do not mix different metals, especially in contact
„
with each other. This will promote galvanic corrosion
and cause rapid failure of the hardware.
Initializing the VR4-UWM will erase the receiver's
„
memory. Retrieve all detection logs before the VR4-
UWM is initialized.
Never cover the Status Light/
Release Valve.
The Release Valve must be able to pop
open if needed and must not be blocked
by tape or paint.
